The pollen tube growth in wide crosses involving Arachis hypogeae (var VRI 2, TMV 7 and TMV 13) and wild Arachis sp. (Arachis stenosperma, Arachis cruziana and Arachis kempmercadoi) have been interpreted among nine crosses. The wide crosses were monitored for pollen attrition and pollen proliferation, being construed that greater levels of genetic distance trigger larger quantum of physiological and physical alterations at various levels of pistil growth. Pollen germination administered greater effect among wide crosses battling poor penetration of pollen tube in the transmitting tissue. The rate of pollen tube proliferation among wide crosses at different levels of pistils was found significant at initial level than at the later stages. The counts of pollen tubes growing down the style were recorded in all the treatment over different level of pistils.
